1-chloro-4-fluoro-isoquinoline CAS 435278-06-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-chloro-4-fluoro-isoquinoline.

CATO supplies 1-chloro-4-fluoro-isoquinoline (CAS 435278-06-1), a certified reference material (molecular formula C9H15ClFN, MW 191.67 g/mol) for analytical method development and quality control.

1-chloro-4-fluoro-isoquinoline (C9H15ClFN) contains a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 1-chloro-4-fluoro-isoquinoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
